“It’s not just a matter of interface design. Apple has built an entire ecosystem to support and enrich the iPad for both customers and developers. To be competitive, a newcomer to the tablet software market needs to replicate or sidestep the need for nearly all of Apple’s major efforts, including synchronization of media and data with Windows PCs and Macs, integration with popular web services, an integrated payment system that customers will actually use at a reasonable rate, a well-stocked music and video storefront, plenty of high-quality third-party apps and fun games, a sophisticated SDK and development environment, widespread retail availability and customer support, and an assortment of good first- and third-party accessories to fulfill common needs (cases, chargers, docks, screen protectors, extended batteries) and give the device new uses (tripods, speakers, styluses, input and output adapters, wall and car mounts).”
